SPECIFIGATION forming part of Letters lfatent No. 721,385, dated February 24, 1.903. Application filedoctober 9, 1902. still-11.126 95, (No mod L) To all whom it may concern: Be it known that I, GEORGE B. PICKOP, a

citizen of the United States, residing atNew Britain, Hartford county, Connecticut, have The object of this invention is to provide in such articles certain features of construction whereby when the windows areclosed' they will be automatically locked in case the operator fails to throw. the fastening devic into action in the usualmanner. I

This automatic locking device is simple, durable, and efiective.

Other advantages will be apparent to the mechanic skilled in the .art from the drawings and-from reading thefollowing specification setting forth the construction of the preferred form'of theinvention. I

In the drawings, Figure l is a plan View of a fastener embodying my invention and portions of a window-sash in such a position that the window may be opened. Fig. 2 is a perspective view of a fastener, the parts being in the position which they will automatically assume when the window is closed. Fig. is a View of the under side of one member of the fastener, a washer being partly broken away. Fig. 4 is a similar view of the same member with the washer removed, the partsbeing shown ina difierent position. Fig. 5 is a front elevation of the fastener when in the normal locked position.

A represents the sash of thelower window,

and B represents the sash of the upper window.

Upon the sash B is secured by screws or other fastening devices the base plate C, which carries a keeper D. This keeper D is somewhat inthe form of a hook having a downwardly-proj ectin g bill D and lateral extensions or shouldersD and D for the purpose hereinafter described.

E is a base-plate screwed or otherwise fastened to the sash Aand supporting the locking device F, which is capable of manual operation as well as automatic. This may be conveniently termed a rotary bolt. The

bolt F is pivotally mounted, for example, by

means of a stud G.

, Hflis a helicoidal cam-like flange, preferably located at the edge of the bolt F.

" I is a suitable handle by which the bolt maybe rotated. Thusfardescribed,saveforthe extensions D D on the keeper,th e parts are well known and operate as follows: The windows are closed and the operator may by swinging the handle I cause the cam H to project back of the bill D of the keeper. This movement not-only causes the windows to be drawn together, but the upper edge of the cam H iswedged under the keeper, so as to tightly lock the windows in the closed position. A reverse movement of the handle I'will throw the cam H out of engagement with the keepenD. Heretofore it has been necessaryfor. the operator to manually operate the fastening device in order to lock the window; but by means of my improvement it is automatically locked at all times, save when the windows are opened or the operator desires to open a window. By givinga slight movement to the bolt F the window may be opened, whereupon the parts will automatically return to their original position, when they are ready to act automatically as a look when the window is closed.

. That this construction may be more fully clear of the shoulder D Obviously th'ewin dows are locked, because the'locking-horn L stands under the keeper-plate or an extension thereof. When the operator desires to open a window, the bolt .F is swung so that the horn-L will stand clear of the keeper, as in Figs. 1 and 4,in'which position it may be caused to dwell. For this purpose the oppo site corners of the hub J are flattened, as

Ice

shown in Figs. 3 and 4. In this position the springs K K are under slight tension and will hold the bolt F in this position until the window is raised. The raising of the window causes the can1-point M to strike underneath the shoulder D (see Fig. 1,) so that the bolt will be rotated to the position of the bolt in Fig. 2, the springs K K bearing against the flattened side of the hub J. It will be observed, however, that the horn L will be raised above theshoulder D before the campoint M strikes the shoulder D so that although the position of the horn L is shifted when the point M does strike it will not be shifted until it has cleared the keeper-plate. Hence the window may be freely raised to any desired height. When the window is closed, the cam-point M will clear the shoulder D but the lower surface of the locking-horn L will engage with the shoulder D This face of the horn L is beveled, as best seen in Fig. 5, so that this engagement will cause the slight rotation of the bolt F in opposition to the tendency of the springs K K until the end of the horn L has cleared the shoulder D whereupon the springs will automatically throw the locking device back to its normal position, in which the horn L stands under the shoulder D of the keeper, as shown in Fig. 2. The cam-point M and shoulder D act as a setting device when actuated by the springs K K. It is apparent that in this manner the window is automatically locked when closed, and it requires no manual act, save the lowering of the window, to accomplish it. Should the operator forget to throw the fastening device around, so as to cause the cam H to come into action, he is provided, nevertheless, with a safety-guard.

It should be understood that the preferable and most eifective method of fastening the windows is to employ the helicoidal cam H; but since it is a common thing for people to forget to manually look their windows the addition of. this safety device provides an effective automatic lock in such cases.

The various details of construction may be modified in a variety of ways without departing from the spirit and scope of my invention. For example, one spring might be employed instead of two.

The parts may be assembled in a variety of Ways, one method being illustrated in which the pivot-stud G is riveted at its lower end against a washer N. This not only aifords a shoulder on which to hold the rivet, but may also extend laterally enough to hold the springs K K in place. This is best seen in Fig. 3 and where the washer is shown dotted in Fig. 4. It will also be observed that supportinglugs P are provided to carry the washer N and prevent it from jamming the springs K K or frictionally engaging the hub J, so as to retard its free movement. Suitable lugs Q Q are also provided to afford convenient bearings for the ends of the springs K K.

\Vhile it is preferable to have the corners of the hub Gr beveled off to provide the dwelling-point, it is obvious that it is not necessary, since the operator could hold the fastening device in the position indicated in Fig. 1 pending the first part of the upward movement of the sash necessary to free the locking-horn L from engagement with the shoulder D It is, however, desirable in order that the operator may first set the bolt F, then have both hands free to open the window.

In the construction herein shown the window is locked, provided it be closed, in all positions of the bolt except those which may be intentionally and manually effected from that wherein the horn L first stands clear of the shoulder D and the position of dwell. (Shown in Fig. 4:.) From the positions between these points the window may be opened, and the bolt will then automatically be in readiness to automatically lock the window when closed.

What I claim is 1. A sash-fastener comprising, a keeper, and a bolt cooperating with one part of said keeper, automatic setting means, and automatic locking means cooperating with another part of said keeper, said setting means being operated by separating the sash members so that said locking means will operate when the sash members are brought together.

2. A sash-fastener comprising, a keeper, and a rotary bolt cooperating with one part of said keeper, a locking-horn carried by the bolt cooperating with another part of said keeper and means for automatically operating the same.

8. A sash-fastener comprising, a keeper, and a rotary bolt cooperating with one part of said keeper, a locking-horn carried by the bolt cooperating with another part of said keeper, a spring 'coacting with said bolt to throw said locking-horn into cooperation with the keeper.

4. A sash-fastener comprising, a keeper and a rotary bolt, extension-shoulders carried by said keeper, a locking-horn carried by said bolt, a setting-cam for cooperating with one keeper extension to move the locking-horn, and a spring for actuating said bolt.

5. A sash fastener comprising a keeper and a rotary bolt, a locking-horn carried by said bolt, a setting-cam for cooperating with said keeper to move the locking-horn, and a spring for actuating said bolt to supplement the action of said cam.

6. A sash-fastener comprising, a keeper and a rotary bolt, an extension carried by said bolt, a fiat spring coacting with a flattened side of said extension or with a flattened corner thereof, means coacting with the keeper for moving the bolt, locking means carried by the bolt which may be brought into position by said moving means and into operation by said spring.

7. A sash-fastener comprising, a keeper, and a bolt, manual means for operating the same, automatic means for locking said parts,

and adapted to cooperate with another part of the keeper, a portion of the bolt serving to set the locking-horn in a position to engage with the keeper when the lower sash is raised relatively to the upper sash, or vice versa, the operative part of the locking-horn being in a higher plane than the lower part of the bolt.
